Toallwkomc'tmyconcern:

Be it known that l 'Jlnomss R. Coon,

a citizen of the United States, residing at Pittsbur%h, in the county of Allegheny and 5 State of ennsylvania, have invented certain new and useful Improvements in Storage Batteries, of which the following is a specification. v

My invention relates to storage batteries and has for an object the provision of novel and improved means for facilitating the circulation of the electrolyte in such atteries.

I will describe one form of battery e m bodying my invention, and will then point out the novel features thereof in claims: In the accompanying drawings, Fig, 1 is a view showing in vertlcal section one form of storage batteriembodying my invention the view being ta en on a plane erpendicular to the planes of the plates an separators.

Fig. 2 is a vertical sectional view of the battery shown in Fig. 1 but taken on a plane parallel to the planes of the plates and sep arators, and looking at the outer surface of one of the outside plates of the battery. Fig. 3 is a horizontal sectional view of the battery shown in Figs. 1 and 2.

Similar reference characters refer to similar parts in each of the several views.

Referring now to the drawings, the reference character 1 designates a jar which is provided as usual with a cell cover 2. Located within the jar 1 are the usual positive plates 3, negative plates 4, separators 8, and ectrolyte, all in accordance with usual and standard storage battery practice.

' The lates and separators are supported in part liy plate rests 11 in the form of ribs at the bottom. of the jar, so that space. is provided below the plates for the horizontal movement of electrolyte. The electrolyte' extends above the plates as usual, thereby permitting horizontal movement of the elec- 'trolyte at this point also. of each plate is provided with a lug 5, and

all of the lugs on the positive plates are attached to one connecting strap 6, while all ot'the In on the negative plates are attached to a similar connecting strap 6. Extending upwardly from the connecting strap 6 is a terminal post 7, while extending upwardly from the connecting stra 6 is a similar terminal post 7, both of w ich posts The upper end project through suitable holes in the cell cover 2 The outer surface of at least one of the outside plates is rovided with vertical ribs- 9, as shown in form vertical passage ways, 10 for the downward flow of the electrolyte between such plate and the adjacent wal of the jar 1. As

ere shown, both outside negative plates are Egovided ,with these ribs, although they may vomitted from one plate if desired.

While a storage battery is being charged, the electrolyte becomes heated due to action between the positive and negative lates, and at the same time oxygen and hydiogen gas are formed in the electrolyte. Both the heating and the generation of gas tend to cause an upward movement of the electrol to between the plates and separators, and t is movement is not seriously impeded because of the looseness of the separators between the plates, and also because vertical passageways are usually provided between the separators and the plates for the express purpose of facilitating such movement. The return movement or downward flow of electrolyte is not ordinarily provided for, however, but in accordance with my invention it Will be noted that such return movement takes place freely owing to the vertical grooves 10 between the ribs 9 and the adjacent wall of the battery cell 1.

One important feature of my invention is that l rovide for .this return or downward flow out the electrolyte with the minimum reduction in the avallable space for the battery element, that is, for the plates and separators, In other words, I provide for such flow with the minimum reduction in capacity for a given size of battery jar.

Although I have herein shown and described only one form of storage battery embodying my invention, it is understood that igs. 2 and 3, which ribs various changes and modifications may be i MES I a vided witheuch ribs.
